Getting Started

The HID Approve SDK enables mobile applications to integrate with ActivID Authentication Server (AS), ActivID Appliance and HID Authentication Service to authenticate users before they can proceed with operations a service provider wants to protect.

Typical use cases are:

Provisioning, when the mobile device is registered for a service and keys are generated
Authentication to a service with a One-Time Password (OTP) generated on the mobile device
Authentication to a service by signing a challenge sent by push notification
Approval of a service operation (for example, a banking transaction) by signing a challenge sent by push notification
Key renewal, allowing the renewal of service keys before expiration without interruption of service

This online guide describes the classes and parameters of the HID Approve SDK public API. It also provides implementation and security recommendations.

It is intended for developers and/or system integrators who integrate software components with the HID Approve SDK and one of the HID authentication servers/service. Readers must be experienced in developing applications for at least one of the supported platforms.

For further details about the SDK, see HID Approve SDK Object Model.
